About Me:
I am a surveyor in South Africa, running a aerial mapping company, 3DroneMapping (www.3dronemap.com). We specialise in GIS terrain mapping and have operated all over Africa.
Please tell us a bit about your UAV interest
We use UAS for aerial surveys to produce topographic, engineering farming and GIS plans.

"Well done boys!"
3DroneMapping has been testing a PPK system for the past year to integrate into our daily workflow. The point of PPK (or Post Processing Kinematic) is not just to improve internal photogrammetric model orientations, but also is general recognised as…
"Im not sure but when doing an Auto mission and given the CAM_TRIGG_DIST parameter, these red boxes are supposed to show the footprint of the image taken."
"Great idea and a fun thing to integrate into your workflow, but sadly will not work here in Africa. We loose on average 2 targets per sortie and those are just paper printed ones. Imagine how irresistible these fancy ones with solar panels will be…"
"Hi Paddy.
Bodies of water do not do well with photogrammetry. There are no tie points on the surface of water for the model to photogrammetrically render itself. Try a test over a pool of water and you will find Mount Everest suddenly appears!

"Hi @kiki boy . You are quite right that Reach is capable of recording data up to those speeds. For a moving rover, this would be well suited as we need as many measurements to accurately plot the rover position in a time span. But for static…"
"@IronDOME, the reference regarding surveyors in Uganda is specifically targeted those in the Fort Portal region that struggled without reliable internet / electricity. Of course graduates from Kampala would have encountered GPS in their training,…"
"What you have is great, Walter and we can wait to see how you integrate it further in to faster moving vehicles. Well done.
But the point is to show that for under $600, you can georeference to survey standards using a really simple and cheap tool."

"Darius Jack, while it is very hard to was what the ping was during the survey, we can estimate that it was in the region of 400-450ms. Our exchange is very antiquated, over populated and 4.5km away on a dodgy copper wire.
Gary, no gazebo this time.…"

"Pascal P., if only OPUS or Centerpoint RTX could use single frequency data. But I dont think it is possible to calculate on such long baselines.
So if you do not tie into an established geodetic control system, locally, your measurements will be in…"

We have been using the L1 only Reach GPS from EMLID for about 2 months. We were first attracted to the fact that it claimed that it was going to be integrated to Pixhawk and would then, via a system of magic, give us centimeter accurate geotagged…
"We had problems to with new RFD900 radios and slow syncing. Was driving us crazy and we thought we would just ave to live with it. But then, out of sheer desperation, I attempted to set the radios to default in Mission Planner. It worked…"
"Cedric, what a small world! Thank you for the kind words.
Now that I look back at this project, I realize how naive I was regarding low altitude photogrammetry. Amazing what experience teaches you and is no substitute for theoretical training."

"By the way, we would love to assist you in future endeavors in Africa. We are based in South Africa but operate all over the continent. Our specialization are topographic surveys and GIS data extraction from low level photogrammetry. With use our…"
"Hi Quan
From what I see, the terrain is very undulating. This will seriously impact the set overlaps and side laps that you set relative to your design or home location. This seems to have reduced the over and sidelaps significantly, resulting in a…"

"Good luck guys, it really looks promising and I wish you all the best with further development. It will be interesting to see what you come up with. Perhaps this is the future for more industrial, working RPAS."
